Giosetta Fioroni was born in Rome in 1932 and she immediately took interest in art: her father was a sculptor and her mother was a painter. Already very young, in 1956, she performed at the Venice Biennale and from that moment on she followed countless exhibitions, both personal and collective, in Italy and abroad.
Her cycle of paintings charcterised by silver subjects, realized in the period between the '60s and the '70s was a success. In 1968 She performed "La Spia Ottica" at the Tartaruga Gallery in Rome.
In the following year she created the first Teatrino, a "toy for adults" in painted wood provided with a lens, through which it is possible to look at a set of miniature objects; in this way she approached the world of fairy tales and legend, opening to the world its personal memory but also the collective one. This interest for legends and spirits continued throughout the '70s, when the artist moved in the country for a long period together with the writer Goffredo Parise: from this experience comes a series of works dedicated to fairy tales and the rediscovery of childhood.
During the '80s, however, she has began a collaboration with writers and poets such as Parise, Ceronetti, Abrasino, Zanzotto and Garboli, making works on paper, books and graphics; in the same period she produces the painting cycle "Il Vero" and a series of pastels and oils dedicated to Tiepolo.
In 1990 the National Institute for Graphics of Rome organized an anthology with all her works on paper and from 1993 she also began to devote herself to ceramics, building important sculptural cycles. In 1993 she took part in the Venice Biennale with a solo show.
